I SUPPORTING-PIN FOR'INSULATORS Application filedoctober 17, 1908. Serial No. 458,173.

Be it known that I, Fnnnnnio A.

0. PER- RINE, a citizen of the United States of America," and'residing at Plainfield, in the county of Unionand State of New Jersey, have invented a new and use 1 Im roved Supporting-Pin for Insulators, of which the metal pins for supporting insulators, par-- ticularly large high tension insulators upon 7 poles-end other structures of wood. or metal,

. in a vertical position to the pole, cross-arm andjgthe main object of my invention is to econstruct a simple and inexpensive'but mechani cally strong supporting for this "A further objeetot' my'inveggt onflsto constructa supporting pin of character .whichshall be especially well adapted for nse on pole tops.

the accompanying drawii gal igur'e- 1 is'a vertical sections'howing the pole top form of my improved pin secured to' awooden pole top; Fig; {tie a front elevation of the same'; .Fig. 3 is a section on the. line 3- -3, Fig. 1. I form the pin of seamless drawn metal tubing of considerably less diameter at its.

top where it has to receive the insulator than at the lower end where it has to' be secured or other support. At its extreme upper end the tubular pin is threaded to be screwed into a threaded thimble cemented or other-- wise secured in the insulator, and below the screw threaded end is formed a shoulder or,

stop for the threaded thimble.

Referring to the drawings, itwill be seen that as there shown, my tubular supportscrew threaded at 10 to'enter a correspond ingly threaded thimble T, (indicated by dotted lines in Fig. 1) which is cemented or otherwise secured in the insulator S, also indicated by dotted lines. I also form just below the upper threaded'end of the pin a shoulder 11 to afford abetter support for I the insulator. In the construction shown, the larger, lower end o the tubular pin may be somewhat flattened one side for appli-- cation to the slabbed'si face "of the top of the pole or other support B, (Fig. 3), and the extreme lower end of the pin is shown closed and flattened down to form' a flange 12 as a continuation of the flattened side of the tube. A hole is formed in this flange 12 and also in the walls of the tube at a point above the flange for the passage of the securing bolts b and b, which passthrough the pole top' orQpther support B.

I clainrasmy invention: a

An insulator pin consisting of a wrought met-a1 tube having its lower end formed with a flange by which it may be secured in a vertical position to the side of a'pole top, but .projecting'above the latter in combination with a transverse securing bolt passing through the flange and pole and another transverse securing bolt passing through the body-of the tube and the pole, substantially as described. 1 In testimony whereof I have signed my "name to this specification, in the presence of rREnERio e. PERRINE.
